Arduino uno r3 is a microcontroller board based on the atmega328. It has 14 digital input/output pins (of which 6 can be used as pwm outputs), 6 analog inputs, 4 uarts (hardware serial ports), a 16 mhz crystal oscillator, a usb connection, a power jack, an icsp header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a usb cable a male to type b or power it with an ac-to-dc adapter or battery to get started.
